MACHINEFOR TREATING SHOE urrnns.

Application filed March 17,1922, Serial No. 544,581.

To all whom it mag concern:

Be it known that I, NoRwoonH. Known- ToN, a citizen of the United States, residl at Rockport, in the county of Essex. an State of Massachusetts, have invented certain Improvements in Machines for Treating Shoe Uppers, of which the-following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to upper treating machines. v The invention is herein illustrated as embodied in a machine especially designed for forming and assembling the 11ppers of stitchdown boots and shoes upon their lasts preparator 1 to lasting.

Heretofore the assembling of stitchdown shoes has been performed by hand, the upper, including usually a counter previously molded with an outturned flange; being placed over a last to the bottom of which a sole has been attached with its margin projecting beyond the periphery of the last.

' The upper is then drawn against the rear end of the last, located, and secured by a tack at the rear end of the last. In this operation the workman sees that the upper is in proper position peripherally of the last, for example by locating the back seam at the center of the rear end of the last, and that the upper is positioned vertically so that there will be enough material of the upper and counter to be worked into the angle between the projecting sole margin and the side of the last, no attempt being made, however, to work the upper into said angle, this being left for the subsequent lasting opera tion which is usually performed by the stitchdown staple laster. y

In View of these conditions, an object of this invention is to provide a machine to facilitate the lasting operation by locating the upper on the last, forming the margin of the upper into the angle in which it is to lie when lasted, and securing the upper to its last preparatory to the lasting operation so that said lasting operation may be performed more expeditiously, effectively, and economically.

Features of the invention consist in means by which the margin of a counter and upper, whether previously molded or not, may be snugly fitted in outturned relation into the angle between the projecting margin of the sole and. the 'side of the last about the heel end of the shoe and may be pressed or beaten in said outturne'd position, and by which the upper may be secured to the last to hold the formed flange and sole in substantially the relation in which they are to be secured together in the subsequent lasting operation.

Thus the lasting of the heel portion of the shoe, usually'performed by the stitchdown staple lasting machine, may be accomplished much easier and with greater celerity because a less number of lasting and stapling operations is required properly to last and,

secure the upper.

As herein shown the upper and counter are held against the last by" a pair of'end embraclng members or wipers normally closed yieldingly against the shoe, and means actmg, preferably by impact, in a downward andrearward direction effects relative move ment between the last and the wipers heightwise of the last to crowd the margin or flange of the upper in outturned relation into the angle between the sole and last. Preferably the flange seating operation, effected by relative movement of the wipers and last,

is performed a plurality of times in each cycle, and as herein shown is performed twice yielding'ly with varying force, the second opera-tion being more powerful than the first. The tacking mechanism operates automatically toinsert a tack through the upper and counter and into the rear end of the last. Preferably the tack is vnot completely driven so as to facilitate its subsequent removal. v 7

Another feature of the invention consists inflange forming means associated with end embracing wipers and upper securing means. As shown herein the flange former or bender consists of a band-like flange arranged to embrace the last inside of the upper and adjacent to the projecting margin of the sole. By relative movement of the wipers and the flange bender the upper about the end of the shoe is spread outwardly and by relative movement of the wipers and the sole heightwise of the last the upper is made to conform to the end of the last and to the angle between the side of the last and the projecting margin of the sole. The upper is then fas tened to the last, for example by a tack driven through the upper and counter and movement to spread the upper at the side of the shoe. Since the resistance of the upper to outward bending is greater at the end than at the sides, this resistance may be utilized to cause the flange former to bend the upper outwardly at the sides prior to its action in bending outwardly the flange at the end.

These and other features of the invention will appear more fully from the following description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

In the drawings,

Fig. 1 is a side elevation of a machine embodying the present invention;

Fig. 2 1s a plan view, partly in section, of the wipers and their operating mechanism;

Figs. 3 and 4 are diagrammatic sectional views illustrating the action of the wipers and pounder in forming a flange on the up er;

Fig. 5 is a side elevation, partly in section, of another embodiment of the invention including flange bending means;

Fig. 6 is a plan view of the construction shown in Fig. 5, the upper being omitted for the sake of clearness;

Figs. 7, 8 and 9 are fragmentary views partly in section, illustrating successive positions of the instrumentalities by which the flange is formed on the upper, seated in the angle between the last and sole, and the upper secured to the last.

Referrin to Fig. 1 of the drawing, the numeral 2 indicates the frame or column of the machine in the upper portion of which is journaled a cam shaft 4 from which the movements of the various instrumentalities with which the machine is provided are derived. Power rotation of the shaft 4 is controlled by a one-revolution clutch of usual type which is operated by a treadle 6 through a treadle rod 8. A work support or jack 0st 10 telescopes into a jack member 12 pivoted at 14' to the column 2. The

post 10 has threaded thereon a sleeve 16 which rests on a jack operating lever 18, pivoted at 20 to the frame. The sleeve 16 has a tongue 22 which engages a slot in the top'face of the lever 18 to prevent turning of the sleeve. The height of the post may be adjusted by lifting the post to free the tongue 22 from the slot, turning the sleeve up or down upon the post and reengaging the tongue with the slot. The post is held from turning by a pin 23 engaging a verti cal slotin the member 12. The last is held by a pin 24 on the post, and the last support, comprising the post 10 and member ,12, is swung about the pivot 14 to carry the last toward and from the machine. When in its outward position as shown by Fig. 1, the post is preferably rigidly supported in order that the up er may be more readil manipulated relatively to the last to p ace it in proper position thereon. For this purpose a cam piece 26 is fastened at 28 to the lever 18 so as to fill the space between the lever and a collar 19 which is loose on the rod 10 and rests on the member 12, thus firmly supporting the post. When the support is moved toward the machine the collar 19 moves away from the cam piece 26 and leaves the post 10 supported only by the lever 18. The lever 18 is operated by a rod 29 which has at its upper end operative connections to a cam (not shown) on'the shaft 4 by which it is uplifted early in the cycle of operation of the machine in a well-known manner. On the lower end of the rod 29 between the lever 18 and stop nuts 31 on the rod, two springs 30, 32 are arranged, the spring 30 being lighter and longerthan the spring 32. When the work support is moved toward the machine it is supported only by the light spring 30 andwhen, in the power operation of the machine, the rod 29 is raised the spring 30 is compressed and the heavier spring 32 comes into action to sustain the support yieldingly but with considerable force. The spring 32 is held centered on the rod 29 by a flanged washer 34. An adjust able stop 36 is provided on the frame to limit upward movement of the lever 18.

A bracket 40 is fixed to-the machine frame by two pins 41, 42 and at its lowerend has three legs 43, 44, 45 (Fig. 2) to the lower ends of which a plate 46 is secured by a bolt 47 passing through a slot in the plate and through the leg 44, and by screw bolts 48, 49 which pass through slots in the plate 46 and are threaded into the legs 43, 45 respectively. The front central portion of the plate 46 is cut away sufiiciently to receive the end of the largest shoe to be treated. Since the plate 46 is connected to the legs 43, 44, 45 by bolts and slots, by loosening the bolts the plate 46 and parts carried thereby'may be adjusted rotarily in the plane of the plate so that a tack which is to be driven in the rear end of the last may be located at one side of the back seam.

Two wiper plates 50, 52 are pivoted at 54 to the plate 46 and are held yieldingly in a normal partly closed position over the opening in the plate by arms 56, 58 pivoted respectively on studs 60, 62 and connected together for equal and opposite movement by toothed segments 64, 66. The outer ends of the arms 56, 58 are urged toward each other by torsion spring-s 68, suitably connected between the studs 60, 62 and the arms 68 as shown. The outer ends of the arms 56, 58 have pin and slot connections 72, 74 with the wipers 50, 52 and hold them in yieldingly closed position-which position is determined and varied by an adjusting stop screw 76. The arms 56, 58 cross each other rearwardly two are preferably provided to'balance the closing force of the wipers.

Mounted in the bracket 40 is a sliding plunger 80 the lower face 86 of which acts as a pounder or heater. The plunger is arranged for up and down movement at an angle of about 60 degrees to the plane of the wi ers 50, 52, and has therefore a substantia component of movement rearwardly. The plunger 80 is slotted at 82 to receive a pin 84 by which its movement is guided. Thebeatlng face 86 of the plun er 80 is substantially parallel to the sole 0 the shoe as presented in the machine and is large enough in area to cover the rear end of the sole including the margin which projects beyond the last bottom. The face 86 is preferably grooved at 87 (Figs. 3 and 4) to avoid contact of the face with the tacks which hold the sole tothe last and have to be removed later. 'To actuate the beater toward the sole a stem 88 is threaded into the upper end of the plunger 80 where it is fixed by a set nut'81. Arranged on the stem 88 are a nut 89, a washer 90, a spring 91, the slotted end of a lever 92 and a clamp collar 93. The lever 92 is pivoted at 94 to the bracket 40 and carries a cam roll 95 which co-operates with a cam 96 having two projections 97, 99, the latter of which extends farther from the center of the shaft 4 than theother. Each rotation of the cam 96 therefore imparts to the plunger 80, through the spring 91, two impulses one of which, preferably the second, is more powerful than the first. It should be borne in mind that the spring 91 is heavier than the.

-handle 100 which may be swung between two. fixed stops 101, 103, the sleeve being retained yieldingly in either position by a sprin plunger 102 engaging suitable notches in a ange on the sleeve-98.

To retract the plunger 80 and maintain the roll 95 in engagement with the cam the spring 91 is utilized. This spring is normally under compression between the washer 90 andthe lever 92 and maintains a hearing projection 105 on the collar 93 in engagement with the top side of the lever 92 at a point rearwardly offset from the bearing of the sprin 91 on the bottom side of the lever. It willv be seen that depression of the stem 88, for instance manually, would cause the lever 92 to rock on the projection 105 and its outerend to move awayfrom the collar 93 to further compress the spring 91. The spring 91 tends, therefore, to maintain the lever 92 and the stem 88 in the normal angular relation shown in Fig. 1 to which they return after power displacement.

The tacking mechanism by which a tack is driven, as shown in Fig. 4, through the upper and counter and into the rear end face of the last, may be of any usual construction and as shown is similar to that disclosed in United States Letters Patent No. 1,023,794, granted April 23, 1912, on application of rrell Ashton. A strip of tacks is fed into a slot with the points of the tacks di rected outwardly. A feed pawl on a slide 112 is operated by suitable connections in-.

cluding a rock-shaft 114 to a rocking mem her 116 pivoted at 41 to the frame and carrying a roll 118 which engages a suitable cam on the shaft 4 by which the tack strip is advanced the amount of the space between tacks in the strip in each cycle of the machine. The tacks are driven by a driver 120 operated by a lever 122 fulcrumed on a pin 124 about which is coiled a driver spring 126. To retract and release the driver a cam roll 128 on the lever 122 is arranged to be engaged by a driver cam 130 which operates the driver in a manner well understood in machines of this class.

In operating the machine above described, the operator threads a loose upper or over the post 10 and places on the pin 24 a last I) having a stitchdown sole or innersole c at tached to its bottom with its margin projecting beyond the last bottom about its periphery. The operator seizes the upper at each side and lifts it up over the last till the edges of the upper and counter d are substantially in the plane of the sole bottom, and adjusts the upper peripherally to I position the back seam centrally of the rear end of the last. Then, holding the upper firmly in position, the operator moves the last and positioned shoe par-ts toward the machine.

The rear end of the last enters the yieldingly closed wipers 50, 52 the front corners of which are rounded and beveled to facili tate its entrance as shown in Fig. 2. The wipers hold the upper to the last along a line spaced vertically from the sole as indicated in Fig. 3. While holding the last back in the wipers the operator depresses the treadle 6 to start the machine. The jack lever 18 is raised by upward movement of the rod 29, compressing the spring 30 and causing the last to be sustained by the spring- 32. The plunger 80 is then actuated downwardly and rearwardly against the sole on the last, depressing the last against the spring 32 and causing the wipers 50, 52 to preferably repeated with increased force to on a stationary table 112.

ensure proper seating of the upper and counter in the angle, and the fastening of the upper may occur either before or-after the delivery of the second blow of the member 80. As shown, a tack e (Fig. 4) is partially driven automatically through the upper and counter and into the rear end of the last between the blows of the member 80.

In some kinds of work a wedge lift has already been attached to the innersole at the time the upper is assembled. When this is the case an extra thickness of material is presented between the wipers-50, 52 and the beating face 86 of the plunger 80, and it is hence desirable to maintain the amount of compression of the beater spring 91 substantially the same to avoid excessive pressure on the thicker work. This is done by swinging the lever 10.0 to the left'against the stop 101 to raise the fulcrum 94 of the lever 92 as above described and as shown in Fig. 1. For work having no wedge lift on the innersole the lever will be swung against the stop 103.

In the form of mechanism embodying the invention as shown in Figs. 5 to 9, the arrangement is such that the shoe is handled right side up and preferably at a downward and outward inclination. This enables the o eratormore easily to determine the relative adjustment of the upper and last prior to operation of the machine. A last I) having an innersole c tacked to its bottom and projecting beyond it as usual in this class of work, is placed with its bottom resting Two flange benders 114, 116 are pivoted to a slide 110, at 118, 120, respectively, one on each side of a U-shaped notch in the end of the slide in which the shoe is located. The benders are geared together at 122 for equal and opposite movement about the pivots 118, and their movement is limited in both directions by a pin 124 engagin a suitable elongated notch in the edge 0 the bender 116. A spring 126 holds the benders normally closed. At their outer portions the benders are shaped to embrace the rear end of a last and along those portions are provided with upstanding flanges 128, 130 the height of which corresponds substantially to the width of the flange to be formed on the upper. The flanges are laterally thin so that the upper may be placed about the last and outside of them in its natural position as shown in Fig. 7. The slide 110 is mounted for movement in guideways 132 formed on the frame 134 of the machine and has a lug 136 extending down between the guideways 132 in a slot 138 Fig. 6). The'lug 136 is notched to receive a pin 140 on a lever 142'which is pivoted to the frame at 144 and carries between its ends a roll 146 which cooperates with a cam 148 on a cam shaft 150. The lever is moved clockwise to hold the slide 110 in its forward position, as shown in Fig. 5, by a spring 152 suitably arranged about its pivot 144.

The rear end of an unmolded upper a is placed about the last outside of the flanges 128, 130 of the flange benders 114, 116, po-

:sitioned peripherally of the last properly to locate the back seam, and held to the last by the operator who then pushes on the shoe to move the slide 110 rearwardly agalnst the spring 152. This movement carries the roll 146 away from its cam 148, the lever 142 assuming the dotted line position 142 of Fig.5. When the machine is started, however, the cam 148 picks up the lever 142 and moves it to its second dotted line position 142", causing action of the flange bender in a manner to be described and retracting the slide 110. The rearward movement of the shoe with the slide brings its rear end between yieldingly closed wiper plates 154, 156 which are pivoted at 158 to a cross-head plate 160 attached to the upper ends of rods 162, 164. The wipers 154, 156 are held yieldingly closed by a spring 166 secured to the head 160 and having its ends arranged to press inwardly on studs 168 secured to the wipers 154, 156 respectively and projecting upward through curved slots 170 in the head plate 160. Beneath the table 112 the rods 162, 164 are pivoted to one end of a link 172 the other end of which is pivoted at 174 to the frame 134. The lower portions of the rods are reduced and pass through a bar 176 journalled in a lever 178 between its ends. One end of the lever is pivoted at 180 to the frame and at the other carries a roll 182 which cooperates with a cam 184 on the shaft 150. Between the bar 176 and the lower ends of the rods 162, 164 strong compression springs 186 are arranged. A tension spring 188 is arranged between the lever 178 and the frame 134 to hold the roll 182 against its cam and to raise the plate 160 and the wipers carried by it. Since the direction of downward movement of the wipers 154, 156 is at a substantial angle to the plane of the sole of the shoe presented on the table 112, the wipers, when depressed, have a component of movement forward lengthwise of the shoe to crowd the outwardly turned margin of the upper closelyinto the angle between the side of the last and the projecting margin of the sole at the rear end of the shoe. The cam 184 has preferably two projections 185, 187

treadle in the usual manner.

which act to impart two successive depressions to the wipers in each cycle of the machine. The projection 187 is higher than the projection 185 so that upon the second depression of the wipers the springs 186 will be more stron ly compressed and greater pressure applled by the wipers to the shoe flange. v

On the plate 160 is a bracket 190 towhich a tacker head 192 is secured by a' pivot clamping bolt 194. Tacks are supplied in any usual manner to the tacker head 192 through a tack tube 196 to be driven by a driver 198 on a driver bar 200 connected by a link 202 to one arm of an angle driver lever 204. The lever is pivoted to the frame at 206 and has on its other arm a roll 208 engaging a driver cam 210. The lever is actuated by the usual driver spring 212 suitably arranged about its pivot 206.

The operator, having positioned the upper on its last and pushed the slide rear-' wardly to bring the rear end of the shoe within the yielding embrace of the wipers 154, 156, starts the machine by depressing a Asthe shaft 150 rotates the cam 1'48 picks up the roll 146 which is then in position 146 and moves the lever 142 to retract the slide 110 and cause the bender flanges 128, 130 to begin to bend the rear portion of the margin of the upper and counter outwardly (Fig. 7). The formation of the cam 148 at 148 causes the benders to move slowly at first. in'eftecting the initial bending of the flange. The resistance to outward bending of the margin is, however, usually greater at the rear end than at the sides. In that case the benders will turn on their pivots 118, 120, causing the upper margin at the sides to be bent outwardly first. .When the opening movement of the benders has been arrested by the pin 124 the benders move bodily rearwardly and bend outwardly the rear portions of the flange (Fig. 8) and when the rearward movement of the bender slide 110 has proceeded far enough to remove the bender from beneath the wipers and head plate 160, these begin to descend because of the action of the cam 184 on the lever 178 which, through the springs 186 and rods 162, 164, e-fl'ects downward movement of the wipers 154, 156. The wipers, because of their component of forward movement relatively to the last in addition to their downward movement, carry the inturned flange of the upper forwardly of the last as well as down.-

, wardly and tuck the angle of the flange snugly into the angle between the side of the last and the projection of the sole, as shown in Fig. 9, this angle being somewhat acute.- in most lasts as shown. After the first depression of the Wipers by the cam projection 185 they are slightly released and immediately-depressedagain more forcibly by the projection 187 to completethe formation aigjd positioning of the upper in the angle.

e driver and a tack e is partially driven through the upper and counter and into the rear end of the last (Fig. 9). The tacker noz'zle may be shifted laterally by loosening the bolt 194 so'that the tack will be driven at one side or the other of the back seam to avoid cutting of the back seam stitches. The machine, having com leted its cycle, stops with the shoe released ing (Figs. 5 to 9) the innersole is shown as havmg a Wedge or beveled liftf attached thereto. The machine will operate on shoes having no wedge lift but in order to secure full effectiveness of the flange benders and full pressure of the wipers it may be desirable to provide, between the sole and the table, a thickness of material substantially equal to that of a wedge lift, for example a metal plate.

The shoe, having been assembled as described, is ready for the operations of staple lasting, and since the upper has been already flanged and worked into the angle in which it is to lie when lasted the labor of staple lasting is greatly reduced, it. being necessary only to insert a few staples to reestablish the upper in the angle and secure it to the projection ofthe sole about theheel-seat.
